Answer:
A nut is a fruit composed of an inedible hard shell and a seed, which is generally edible. In general usage and in a culinary sense, a wide variety of dried seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.
Answer:
x=4
Step-by-step explanation:
8x - 7 =2(2x +7) - 5
8x - 7 =4x +14 - 5
8x - 7 =4x +9
8x - 4x =9 +7
4x =16
x=16 :4
x=4
Answer:
-21/4 + 3s/4
Step-by-step explanation:
Answer: 2.14 %
Step-by-step explanation:
Given : pH measurements of a chemical solutions have
Mean :
Standard deviation :
Let X be the pH reading of a randomly selected customer chemical solution.
We assume pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).
The z-score for the normal distribution is given by :-
For x = 6.74
For x = 6.76
The p-value =
In percent,
Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%
